Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
6-bromo-2-methoxy-quinazoline (CAS 1260785-32-7), molecular formula C9H17BrN2O and molecular weight 249.15 g/mol, is a CATO reference standard with documented purity and traceability.
6-bromo-2-methoxy-quinazoline (C9H17BrN2O) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 6-bromo-2-methoxy-quinazoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
